Patent CA-2145877-A1 (CA)
Inventor: BEYMER BRIAN A
IPC: G08G1/16
Filed: 1993-09-29
Abstract: A method, apparatus, and system for transmitting and receiving an electromagnetic data signal in a moving, linear chain for use primarily in collision avoidance.  Each unit in a chain of units has a processing unit interconnecting a directional receiving element (10e), directional low power transmitting element (12E), a deceleration detector for the unit, and a deceleration detector for a preceding unit in the chain.          In a simple form, motor vehicles (D-H) are the units.  If the invention detects deceleration of a preceding vehicle deceleration of itself, or an identifiable signal from a preceding vehicle such as a blue light, it causes a rearward facing blue light to illuminate.  This blue light indicates to following motorists that the perceived vehicle is decelerating or that a vehicle somewhere in front of it is decelerating.  The blue light also may be received by another vehicle equipped with the invention and consequently be transmitted rearwardly.  In a general form, a data encoded high frequency signal is transmitted rearwardly from a vehicle.  This signal contains information relating to deceleration of any preceding vehicles (Chain Brake) and of the transmitting vehicle (Brake).

Patent CA-2152219-A1 (CA)
Inventor: GLEICHMAR GERT
IPC: C04B7/24
Filed: 1995-06-20
Abstract: The invention refers to a process of treatment and environment-friendlyutilization of asbestos-cement products including a thermal process to transform the asbestos component. Inventively, this is achieved by a coarse reduction of the asbestos-cement products under black side conditions with maintained vacuum. Then the material is ground to asbestos-cement meal and fed to the flame zone of the rotary kiln of a cement clinker production line. Depending on the fuel type used, the portion of fed asbestos-cement meal varies between 2 and 5 %, related to the amount of cement raw meal, substituting 2 to 5 % of the cement raw meal mix at a time. The thermal transformation of the asbestos component takes place with temperatures of approx. 1800 °C in the burner zone. The modified residualsubstance becomes a constituent of the cement clinker due to assimilation in the kiln charge.

Title: Compositions for melt processing high temperature superconductor
Inventor: WOOLF LAWRENCE D
IPC: C30B29/22
Filed: 1996-04-02
Abstract: A melt  processing method  for  bulk  or  thick  film fabrication of RE123 superconductor material includes the steps  of  using  Nd  in  the  RE123  to  increase  the recrystallization speed of the RE123, and using a heavy rare earth in the RE123 to establish the peritectic melting point of the RE123 somewhere below the melting point of silver. Within these requirements, the method essentially includes heating the RE123 above its peritectic melting point, and then cooling the resultant decomposed material to recrystallize the RE123.  The heavy rare earths to be used for lowering the RE123 peritectic melting temperature include Lu, Yb, Tm or Er or mixtures thereof.  The addition of RE211,  silver and the use of a  low oxygen partial pressure also contribute to a lowering of the melting point of the RE123.  When using Nd to accelerate the processing time, the RE123 can include a first component of Nd1-zRz123 and a second component of Nd1-yRy211.  For these components, R is one of the heavy rare earths,  z is between 0 and approximately 0.9, and y is between 0 and approximately 0.9.

Patent CA-2173375-A1 (CA)
Inventor: BASHARK LARRY T
IPC: B30B15/26
Filed: 1990-08-23
Abstract: An electronic control for a motor which eliminates the motor centrifugal switch and more particularly a control for a domestic refuse compactor which permits the user to control the approximate full trash bag weight and obtain more compaction from a split phase induction drive motor.  A ferrite core sensor on the main winding of the drive motor samples the lagging phase angle of the motor main winding current during a compaction stroke.  A low force cycle is achieved by terminating the stroke as soon as phase samples fall below a threshold defined at the start of each cycle by a locked motor main winding phase sample acquired prior to starting the motor.  A medium force cycle terminates the stroke when compaction forces exceed the main winding breakdown torque.  A high force cycle is achieved by reactivating a motor start winding when compaction forces exceed the main winding breakdown torque and terminating the stroke as soon as the phase samples exceed a threshold defined at the start of each cycle during motor starting.  The control uses programmed referencing techniques to eliminate factory precalibration.
Patent CA-2177228-A1 (CA)
Inventor: MALEK MICHAEL L
IPC: G01N21/27
Filed: 1996-05-23
Abstract: A luminometer for determining the composition of a specimen sample  includes  an  annular guide path for  sample  containing cuvettes within a light tight housing.   A rotor moves spaced segments  through the guide path with the cuvettes positioned between the segments.  The luminometer further includes one or two detector assemblies coupled to the housing and positioned to view and detect light emitted by cuvettes as they pass along the guide path between segments.  A cuvette is advanced around the housing via the rotor and rotor segments and when the cuvette reaches a predetermined position on the housing, a reagent, such as a base, is added to the cuvette to initiate a chemiluminescent reaction within the cuvette and provide an emission of light energy in a predetermined spectral  range.    The  luminometer  has  a  waste aspiration probe to remove the contents of the cuvette after it passes the detector.  A cuvette elevator moves a sample containing cuvette into the guide path between segments and an exit chute removes cuvettes after their contents have been aspirated.   The luminometer permits continuous uninterrupted sample testing when coupled to an incubation chamber in which the cuvettes receive samples and test specific reagents before they are moved into the luminometer by the elevator.
